In the Western world, we have traditionally classified bodies into three types. I want to provide you with a description of each of them here:

1. Ectomorph

An ectomorphic body type is skinny and has narrow hips and clavicle, small joints, a thin muscle belly, and long limbs.

I like to call the ectomorphs the skinny bastards. Ectomorphs lose weight easily and gain weight, including muscle, with great difficulty.

Ectomorphs benefit most from a nutritional regiment that comprises lots of eating, as many as 4,000 calories per day, including a balance of proteins, fats, and carbs. And they benefit from exercise regimen that includes very light cardio paired with heavy strength training and lots of rest.

2. Mesomorph

A mesomorph body type is well built and has wide clavicles, a narrow waist, small joints, and a long and round muscle belly.

I like to call the mesomorphs the lucky bastards. Mesomorphs maintain a neutral weight and comprise the majority of great body builders.

Mesomorphs benefit most from a nutritional regiment that comprises moderate eating, including a balance of proteins, fats, and moderate carbs. And they benefit from exercise regimen that includes moderate cardio paired with moderate strength training and moderate rest.

3. Endomorph.

And an endomorph body type is blocky and has big joints, wide hips and clavicles, and short limbs.

I like to call the endomorphs the fat bastards. Endomorphs gain weight easily and lose weight with great difficulty.

Endomorphs benefit most from a nutritional regiment that comprises very light eating, 2,000 or less calories per day, including a balance of proteins, fats, and a very limited amount of carbs. And they benefit from exercise regimen that includes heavy cardio, high intensity interval training whenever possible, and lots of activity.
